“I’m like an old race horse – it’s not like I’m ancient ancient, but these things are sort of worn out a bit,” says Mick, rubbing his shoulders. He’s has wristbands for his tendonitis too.

“I’ve got a deep-freeze in my room in order to do what I’m doing... you take care of yourself.”

He’s 70 this month but insists: “I’m not letting up any – I’m playing harder than I ever played, apparently.”

Fleetwood Mac descend on the Isle Of Wight Festival next week for 91st performance in current On With The Show tour.

It’s been an epic journey for Mick, Stevie, 67, bassist John McVie, 69, his ex-wife Chrissie, 71, who sings and plays keyboards, and singer-guitarist Lindsey Buckingham, 65. And not without its battle wounds.

"It’s odd to think on that on some strange level Stevie and I could still possibly be a work in progress. In a way it’s sort of touching, isn’t it?”

Stevie is less convinced. “He is who he is,” she says. He and I have our rifts. We don’t agree on anything. And that’s just the way it is.

“Has he changed and become this really graciously, charmingly loving guy all of sudden? No. He never will. He’s always gonna be Lindsey.”

But they’ve clearly found a way to make it work. An 18th world tour is an accomplishment only rivalled by the likes of the Rolling Stones.

Mick says: “Mick Jagger literally doing somersaults and running around the stage at 72 is truly astonishing. We’re much more consistent. We’re in good shape. And all the voices are really very, very intact. Which is not always the case.”
